Evaluating battery aging on mobile devices
Proceedings of the 52nd Annual Design Automation Conference, 2015Battery-related problems in mobile devices have been extensively investigated in both industry and literature. In particular, battery aging is a critical issue, since battery lifetime decreases as usage time increases. Battery aging primarily causes inconvenience to users by necessitating frequent recharging, and also affects the accuracy of power ...

Battery Degradation and Ageing
2001Batteries are subject to degradation in storage due to a variety of chemical mechanisms, such as limited thermal stability of materials in storage, e.g. silver oxide in silver - zinc batteries, or corrosion of metal electrodes, e.g. lead in lead - acid batteries or lithium in lithium / thionyl chloride batteries.

Ageing of rechargeable lithium batteries
Journal of Power Sources, 1985Abstract Ageing of secondary lithium button cells is reported for two cases: cycling and storage. In respect of cycling, 120 deep cycles have been achieved with LiAl/dioxolane — LiClO4/NiPS3 cells; the rate of ageing is related to both the charge cut-off potential and the nature of the cathodic material. After storage at room temperature for one year

VRLA battery aging characteristics
Proceedings of Intelec'96 - International Telecommunications Energy Conference, 2002In the framework of an extended test program to better understand the behavior of valve-regulated lead-acid (VRLA) batteries under various operating conditions, FIAMM reports on a comparison of thermal runaway tests carried out on two different 48 V batteries. This testing involved both new and five-year field-aged cells taken from a telecommunications

Aging of lithium-ion batteries
Journal of Power Sources, 2004Abstract Lithium-Ion (liquid electrolyte) batteries are considered as long life and reliable systems. This paper: • introduces discussion about aging and degradation mechanism both for storage and cycling, • illustrates the proposed phenomena from results based on several years experimentation and obtained on scale one cells, •

Battery aging management for Fully Electric Vehicles
2018 European Control Conference (ECC), 2018Nowadays lithium-ion batteries are the standard power source for electric transportation applications. Lithium-ion batteries are subject to aging and matching the battery life with the vehicle life is still one of the unresolved challenges limiting the large-scale spreading of electric vehicles.

Aging and performance on the luria-nebraska neuropsychological Battery
International Journal of Neuroscience, 1983The Luria-Nebraska Battery has been shown to be a valid measure of neuropsychological functioning in younger adults; however, little validity research with the elderly has been reported. Seventy-eight healthy elderly adults (mean age = 72.2 years) were tested with the Luria-Nebraska Battery and 92% of the profiles were found to be within normal limits.

Repeated Measures Battery for the Aged
Proceedings of the Human Factors Society Annual Meeting, 1987A battery of 29 reliable, valid and repeatable cognitive and psychomotor paper-and-pencil tests, with each test measuring a specific construct, was used to assess the performance of 48 older males and females. These subjects were divided into three separate age groups: 55–60, 65–70, and 75–80 years.

Report on Lithium-Ion Battery Ageing Tests
2020Lithium-ion battery ageing modelling and prediction is one of the most relevant topics in the energy storage research field. The development and assessment of reliable solutions are not straightforward, because of the necessity to acquire information on the cell ageing processes by employing very time-consuming tests.

Aging mitigation of power supply-connected batteries
Proceedings of the 2014 international symposium on Low power electronics and design, 2014Battery-operated portable electronics, from smartphones to notebook computers, are generally sold with a dedicated power supply. The power supply operates the device and also charges the built-in battery. Most users are concerned about the battery aging while the device is operated by the built-in battery.
